Hair straightener

A fan assembly comprising an air inlet, at least one air outlet, an impeller, a motor for rotating the impeller to draw air through the air inlet, at least one heater assembly, and a user interface for allowing a user to select a speed setting for the motor from a user selectable range of speed settings, and for allowing a user to select one of a first and second operational mode of the fan assembly. A rotational speed of the motor is set depending on the user selected speed setting, and is selected from a first range of values when the first operational mode of the fan assembly has been selected, and from at least one second range of values when the second operational mode of the fan assembly has been selected, with each value within each of the range of values being associated with a respective speed setting.

Fan assembly

A fan assembly for creating an air current includes a nozzle mounted on a base. The base comprises an outer casing, an impeller housing located within the outer casing, the impeller housing having an air inlet and an air outlet, an impeller located within the impeller housing and a motor for driving the impeller to create an air flow through the impeller housing. The nozzle includes an interior passage for receiving the air flow from the air outlet of the impeller housing and a mouth through which the air flow is emitted from the fan assembly.

A support assembly for a surface treating appliance includes a roller having one or more tires, wherein the one or more tires are fused to the roller. The roller can include a polymer such as polypropylene and may also include a glass filled impact modified copolymer such as a 20% glass filed impact modified copolymer. The tires can include a thermoplastic elastomer such as a modified polymer including a mixture of polypropylene and an ethylene propylene diene monomer. The thermoplastic elastomer may have a hardness of from 55 to 95 Duro measured on the A scale, more specifically from 70 to 79 Duro on the A scale or from 80 to 95 Duro on the A scale.

Support assembly

A cleaning appliance includes a main body, a handle assembly and a hose. The handle assembly includes a tube and a gripping portion fixedly attached thereto. The hose has one end attached to the main body. The tube is movable relative to the main body between a stored position in which at least a part of the tube lies within the hose and an extended position in which the gripping portion can be used to manipulate the cleaning appliance in use. By providing such an arrangement, the handle assembly and the hose can be stored compactly. When the user wishes to store the cleaning appliance, the tube can be retracted inside the hose for storage. When the tube is extended, the gripping portion is at a convenient height to be manipulated by a user.

The base comprises an outer casing, an impeller housing located within the outer casing, the impeller housing having an air inlet and an air outlet, an impeller located within the impeller housing and a motor for driving the impeller to create an air flow through the impeller housing. The nozzle includes an interior passage for receiving the air flow from the air outlet of the impeller housing and a mouth through which the air flow is emitted from the fan assembly. A flexible sealing member is located between the outer casing and the impeller housing.
